<p><P>PROBLEM TO BE SOLVED: To provide a fluid discharge pumping device capable of discharging fluid stored in a cylinder to the outside of the cylinder by a predetermined amount even with a simple constitution having the low manufacturing cost. <P>SOLUTION: The fluid discharge pumping device 1 is equipped with a cylinder 10 which is equipped with an inflow port 11 to flow the fluid in, an outflow port 12 to flow the fluid out, a piston moving part 13 wherein the piston 21 can reciprocate, and an insert port 14 for a piston member to insert the piston member 20, the piston member 20 which can reciprocate by driving of a motor drive mechanism 60, and an outflow valve mechanism 40 attached to the outflow port 12. The cylinder 10 is detachably supported by a control part 70, and the piston member 20 is detachably connected to the motor drive mechanism 60 through a piston support member 65. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
